Output gap and consumption risk on the cross-section of stock returns in Korea

초록

We examine if output gap can be the conditioning information for consumption-based asset pricing model in the Korean stock market. In an effort to empirically explain the cross-sectional variation of stock returns with economic equilibrium model, our conditioning variable, output gap, enables consumption capital asset pricing model (CCAPM) to explain a substantial variation in the cross-section of stock returns in Korea. In addition, the conditional version of CCAPM with output gap as a conditioning variable can explain the cross-section of stock returns about as well as the Fama-French three- and five-factor model when using future consumption growth. Asset's riskiness is determined by the correlation with consumption growth conditional on the business cycle measured by the output gap. (JEL G12).
